Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of centrally acting agents targeting neurological pathways. Its spirocyclic structure and functional groups make it valuable for constructing complex heterocycles found in bioactive molecules. Commonly employed in medicinal chemistry for lead optimization, especially in projects involving GABA analogs or neuroactive drugs. The tert-butyl carboxylate group allows for easy deprotection and further derivatization, enabling efficient synthesis of amide or ester derivatives. Also utilized in research settings to explore structure-activity relationships in spiro-based scaffolds.
